For the simple decomposition reaction AB(g)→A(g) + B(g) rate = k[AB]2 and k = 0.55 L/mol·s. How long will it take for [AB] to reach 1/3 of its initial concentration of 1.50 M?

Peroxynitric acid (HOONO2) is an unstable molecule that decomposes to nitric acid and oxygen: 2HOONO2(aq) → 2HNO3(aq) + O2(g)When the concentration of peroxynitic acid is graphed against time, the resulting plot is curved, but if the logarithm of this concentration is plotted, we instead get a straight line. Based on this, which statement is true? a)  This decay is a second order in peroxynitric acid. b)  The slope of the straight-line graph is the rate constant. c)  One needs the concentration of peroxynitric acid to calculate its half-life. d)  The rate law appears to be of the form -Δ[HOONO2]/Δt = k[HOONO2].

Enter your answer in the provided box. For the simple decomposition reaction AB(g)→ A(g) + B(g) rate = k[AB]2 and k = 0.10 L/mol·s. How long will it take for [AB] to reach 1/3 of its initial concentration of 1.50 M? t =_____s

Predicting relative forward and reverse rates of reaction in a dynamic... Nitrogen and hydrogen react to form ammonia, like this: N2(g)+3H2(g) — 2 NH3(g) Imagine 61. mmol of NH3 are added to an empty flask, and then answer the following questions. What is the rate of the reverse reaction before any NH3 has been added to the flask? What is the rate of the reverse reaction just after the NH3 has been added to the flask? What is the rate of the reverse reaction at equilibrium? How much NH3 is in the flask at equilibrium? Zero. Greater than zero, but less than the rate of the forward reaction. Greater than zero, and equal to the rate of the forward reaction. Greater than zero, and greater than the rate of the forward reaction. Zero. Greater than zero, but less than the rate of the forward reaction. Greater than zero, and equal to the rate of the forward reaction. Greater than zero, and greater than the rate of the forward reaction. Zero. Greater than zero, but less than the rate of the…
